I'm pretty sure the person lives while separated. Remember when Law was holding just the head of one of the marines and it was talking?

Edit: Now that you mention it, the fullbody suits those soldiers were wearing is somewhat reminiscent of Law's crew. Maybe they've been tasked to do something for him and the strawhats were captured unbeknownst to Law.
